Embodiment Construction

[0012] 1. Experimental plan

[0013] 1. Experimental materials

[0014] Take 100g of green tea, 200g of dried ginkgo leaves and 50g of dried corn silk, add 500g of water and decoct for 10 minutes, filter and remove the filter residue after cooling, and keep the filtrate as plant extract.

[0015] The loquat fruit is produced in Putian City, Fujian Province, and the variety is called "Jiefang Zhong". After being picked, it was transported back to the laboratory immediately. Select fruits with the same size, no disease and mechanical damage, put them in an oven for heat treatment at 48°C for 3 hours, take them out and cool them, soak them in 1% chitosan solution containing 100 μmol / L vitamin E for 5 minutes, take out the fruits and put them 300g of fruit is soaked in 500g of plant extract solution for 10 minutes, dried and packaged for storage. The packaging bag is a 0.025mm thick polyethylene plastic bag.

Abstract

The invention discloses a storage and preservation method for loquat fruits, which comprises the following steps: (1) selecting loquat fruits with uniform size, uniform maturity and no mechanical injury, putting into a polyethylene plastic bag, and carrying out heat treatment in a 48 DEG C drying oven for 3 hours; (2) cooling, and immersing the loquat fruits in a 1% chitosan solution containing 100 mu mol/L vitamin E for 5 minutes; immersing every 100g of loquat fruits in 100-200g of plant extract water solution for 8-12 minutes; and (3) naturally drying at room temperature, storing the fruits at 8 DEG C for 3 days, storing at 4 DEG C for 3 days, and storing at 1 DEG C. The combined storage and preservation method is reasonable in design; and compared with the method of simply storing loquat fruits at low temperature, the method disclosed by the invention can effectively avoid cold injury of the loquat fruits, control the rotting rate of the loquat fruits after collection, and prolong the storage period.

Description

technical field [0001] The invention belongs to a fruit storage method, and relates to a storage and preservation method for horticultural products, in particular to a storage and preservation method for loquat fruit. Background technique [0002] Coating film preservation is to cover the surface of food by wrapping, coating, etc., providing selective gas barrier, moisture barrier, content loss resistance and harmful influence of the external environment, inhibiting respiration, delaying subsequent aging, and inhibiting the growth of surface microorganisms. Improve storage quality and other functions, so as to achieve the purpose of food preservation and prolong its shelf life. [0003] Vitamin E is a fat-soluble vitamin. It is a non-enzymatic antioxidant located in the membrane system in plants. It plays an important role in protecting cell membranes from free radicals. It is especially rich in the double membranes of mitochondria and chloroplasts in plant cells. . At pre...
